"Unterminated String literal" error when append component

cike,

actually, in my case I'm able to do it and it's possible ;-)

I'm adding one component inside another, both of them are custom components

<div>
        <div id="hottopics"></div>
    </div>
    <@liaAddScript>
        ;(function($){
        // add another component
        
        var topics = $('#hottopics');
        
        topics.append('<@component id="test-plug-to-js"></@component>');
        

        console.log('i got through!');
        
        })(LITHIUM.jQuery);
    </@liaAddScript>

the only trick is to strip-out white-spacing and line breaks in test-plug-to-js component.

 Wrap your component in 

<@compress single_line=true>...</@compress>

to get rid off line spacing
